Abstract
A compressed gas cylinder assembly is disclosed which includes a metallic cylinder body having an upper end portion with handles and a flow control valve, and a lower end portion with a convex surface from which depends a lower support ring. A non-conductive annular collar surrounds the lower support ring of the cylinder body, and a conductive foot ring connects the annular collar to the lower support ring of the cylinder body, providing a conductive path to ground for the metallic cylinder body.
